Multicentric experience with combined hemodialysis/hemoperfusion in chronic uremia.

A multicentric study was carried out to investigate the safety and effectiveness of long-term treatment of chronic uremic patients by a regular combination of hemodialysis and charcoal hemoperfusion. 39 RDT patients from five dialysis centers were treated for up to 12 months. The combined treatment proved to be safe, well tolerated and effective in improving certain dialysis-resistant uremic signs, mainly severe peripheral neuropathy, asthenia, anorexia, nausea, lack of well-being and relapsing pericarditis. There was also a marked decrease, after several weeks of combined treatment, in plasma values of urea, uric acid and creatinine.

Function of the kidney in adult patients with Cooley's disease. A preliminary report.

The function of the kidney in adult subjects with Cooley's disease has been hitherto inadequately investigated. In 10 patients suffering from thalassemia major, glomerular filtration rate, renal plasma flow, renal blood flow have been studied, together with urine concentration capacity. The authors emphasize certain pathological changes, such as the increase in renal plasma flow and the failure of the urine concentration ability. On the basis of renal biopsies, two pathogenetic theories are discussed: the functional impairment of the coutercurrent system and fibrosis of the medullary tissue.

Vascular endothelial growth factor (VEGF) in human tooth germ center.

Many oncogenis and tumour suppressor genes found inside normal and pathological cells are fundamental for the processes of development, proliferation and tissue differentiation. The purpose of our study is to show the presence and a possible relationship of the VEGF protein during different phases of the development of human dental germ centers. After cephalometric investigation in 8 orthodontic patients with a mean age of 13 years, (4 females and 4 males), hyperdivergence of the third molars were extracted. The 40 surgical samples were tested with monoclonal human anti-VEGFs antibodies carrying out a semi-quantitative analysis to look for a positive reaction. Reaction for anti-VEGF antibodies was detected in normal embryological tissues and in microvessels near odontogenic cells. During different phases of embryologic development of the dental bud our search showed intracytoplasmatic positive immunoreactions both in the ameloblastic and odontoblastic cells. Additionally, a positive reaction was observed for the VEGF protein in the cells of the stellate reticulum and in those endothelial tissue surrounding the microvessels in all the samples examined.
